Solar Powered Grid Based on Reused PCs

Abstract

In this paper, we propose a way to reuse obsolete older model PCs as a grid in keeping with green IT. A grid can create a high performance environment consisting of ordinary PCs. However, it has continuous energy requirements. This is undesirable in terms of environmental concerns, because of the increased CO2 emissions from generating the required electricity. Therefore, this study aimed at realizing a grid powered using solar power to overcome the disadvantage, while reusing obsolete older model PCs. We studied we measured outdoor operating time of the system using only a master node PC using our new power management method. We operated this system, which was composed of three reused PCs, outdoors. We found an efficient charging method that can be used during system operation, and were able to identify priorities for future work.
